MATARAM, Indonesia (Reuters) - Rescue workers found chaos and destruction across the Indonesian resort island of Lombok on Monday after a magnitude 6.9 earthquake killed at least 91 people and prompted an exodus of tourists rattled by the second powerful quake in a week.

The National Disaster Mitigation Agency (BNPB) said the death toll was expected to rise as information came in from areas where thousands of buildings collapsed or were badly damaged, especially in the north, the quakes epicenter.
